1. Field of the Invention
This invention relates to carts for moving a variety of goods and more particularly to a cart which is readily folded for transport and storage.
2. Prior Art and Objects of the Invention
Skis are notably difficult to handle being long and awkward to carry. Along with the skis, ski boots and poles, an equipment bag is also essential to carry such items as goggles, caps and gloves. With all of this equipment to carry, the trip from the parking lot to the lodge of a ski center can be difficult and precarious.
In playing golf, carts have long been an essential part of golf equipment. However, carts which are pulled to carry equipment including golf clubs and golf bag, are not easily transportable in an automobile.
A cart on which all the equipment could be securely stowed and which could be easily pulled with all the necessary sports equipment on it would fill a long felt need. Such a cart would need to be light and compact. Of greatest importance, it would have to be capable of being folded so as to require minimal space when not in use and when being transported in an automobile. While skiing the cart could be compactly stored while with golf, the cart would be used during the playing of the game. In both situations, the cart could be easily carried and readily stored when not being used.
It should be understood that many other uses for a compact cart, besides golf and skiing, are possible and in fact are almost unlimited. However, skiing and golf provide two areas of use encompassing both winter and summer. Such a cart is not known or available.
Accordingly, it is an object of the present invention to provide a cart for carrying a variety of equipment.
It is another object of the present invention to provide a cart for carrying ski and snow board and golf equipment.
It is another object of the present invention safely to retain articles to prevent others from falling over the articles if placed to one side.
It is another object of the present invention to provide a cart that is light and is easily folded into a compact unit for storage.
These and other objects will be apparent to those skilled in the art based upon the description of the preferred embodiment.
A cart is provided for transporting various items most particularly sports equipment such as ski and snow board and golf equipment. The structural base for the cart is a frame which includes a cross bar and two wheel bars generally parallel to one another and extending substantially at right angles from the ends of the cross bar. Journals are mounted to rotate on the wheel bars and wheel plates extend from the journals to which the wheel plates are secured. The wheel plates taper from the journal to an outside end which is generally rounded. An axle is secured to each of the wheel plates at the outside end and a wheel is mounted on each axle to rotate. On these two wheels, the cart can be readily pulled.
To use the cart, the wheel plates are placed parallel to one another and locked into position. For storage purposes, the wheels can be rotated toward one another against the frame and are then locked in that position.
A handle extends from the frame and the handle folds downwardly and backwardly for storage. A cradle is mounted on the handle to retain items in place and the cradle may be modified to accommodate different items. Straps may be used to secure the various items to the handle and on the shelf.
A shelf is mounted on the cart on the opposite side of the cart from the wheels to rotate generally ninety degrees from a vertical position to a horizontal position with the cart in an upright position. A locking means is used to retain the shelf in its lower or operating position.
FIG. 3. is a pictorial view from the side and rear showing the wheels in their stored position but with one wheel shown in italics in its operating position and also showing the handle folded down for storage with the handle in its upright position shown in italics.
Referring now to
For purposes of reference, the back of the frame 11 is where the wheels 21 are located and the front of the frame 11 is where the shelf 15 is located.
The wheel assembly 19 is mounted on each of the two wheel bars 25. Each wheel assembly 19 includes a journal 31 mounted on each wheel bar 25 so as to rotate on the wheel bar 25. The journal 31 has a lower end 33 adjacent the lower end 29 of the wheel bar 25 and an upper end 35 opposite from the lower end 33. An end collar 37 is secured to the lower end 29 of each wheel bar 25 by a set screw 38. A spring 39 is placed between each end collar 37 and the journal 31 to force the journal 31 away from the end collar 37. An upper collar 41 is secured to the upper end 27 of the wheel bars 25. The upper collar 41 has lugs or projections 43, as shown in
A wheel plate 47, which is part of the wheel assembly 19, is secured to each of the two journals 31. The wheel plate 47 generally tapers from the journal 31, to which it is secured, to a rounded end 49. At the rounded end 49, an axle 51 is secured to the wheel plate 47 on which the wheel 21 is mounted to rotate. The two wheels 21 so mounted serve to roll the cart by pulling. When the wheels 21 are set to serve as a basis to roll the cart, the two wheel plates 47 are parallel as shown in FIG. 2. When the cart is being stored, the wheels 21 are folded against the frame 11 as seen in FIG. 3. and are aligned with one another. The wheels 21 may be moved from the operation position, to the storage position as has been previously explained, by depressing the journal 31 against the spring 39 to release the lugs 43 from the indentations 45.
The shelf or platform 15 is centrally mounted on the handle 13 slightly forward of the two wheel bars 25. A hinge 55 is used to secure the shelf 15 to the handle so that the shelf 15 can be rotated up against the handle 13 and down approximately ninety degrees when in use. The shelf 15 may be mounted to rotate on the cart in any number of ways.
When the shelf 15 is its lowered position and particularly when is use, it is important that the shelf 15 not rotate back up toward the frame 11 as might occur if the shelf 15 struck a curb. To assure that the shelf 15 will not improperly rotate when is use, a lock 57 is provided as seen in
The handle 13 in its operating position can best be seen in FIG. 1. The handle 13 has a lower section 73 and an upper section 75. The lower end 77 of the upper section 75 is secured to the upper end 79 of the lower section 73 by a retaining assembly 81. The upper section 75 and the lower section 73 are aligned with one another but are offset from one another. A hinge member 83 is secured to lower section 73 of the handle 13 towards the upper end 79 of the lower section 73. The upper section 75 of the handle 13 is mounted to pivot on the hinge member 83. A retaining member 85 is mounted to slide on the upper section 75 of the handle 13 and the retaining member 85 includes a socket 87. The retaining member 85, with the upper section 75 of the handle 13 in the operating position, slides downwardly so that the socket fits over the upper end 79 of the lower section 73 of the handle 13 thereby retaining the upper section 75 as a rigid extension of the lower section 73. By lifting the retaining member 85 upwardly, the upper section 75 of the handle 13 may be folded over the back of the cart as seen in FIG 3.
The upper section 75 of the handle 13 at its upper end 89, most remote from the lower section 73, includes a hand grip 91. The lower section 73 is secured to the frame 11 as has been previously described and, as seen in
